标志性的“聊天系统”机制网络应用程序
让我来设置一下。我在一家中型教堂从事声音/多媒体工作。有时，平台需要与音响室或多媒体室进行通信，而我们不想对此表现得太明显。我们尝试过对讲机，但坦率地说，我们的运行温度非常高，即使戴着耳塞，我们也听不到对讲机的声音。 另外，我们不能使用短信；实在是太慢了。
目前的工作思路是使用某种平板电脑（例如 iPad）来运行一个极其简单的应用程序，只需点击图标即可快速传递消息。例如，音乐总监可以点击“声音室”图标，该图标将让位于显示与声音相关的项目的特定于上下文的屏幕。然后他可以点击“钢琴”，然后“讲坛监听”，然后“向上”，然后“很多”，或者“鼓”，“钢琴监听”，“向下”，“一点”。看看我要去哪里？看起来原生应用程序又快又酷（而且很容易赚钱），但如果不是必须的话，我不想学习 iOS 开发。我宁愿它只是一个网络应用程序，这样我就可以在 Xoom 上运行它（如果我购买了一个）。 ;-)
过去几年我一直在学习 Rails，但我还没有尝试过像 EventMachine 这样的东西。我发现“Juggernaut”可能适合账单，但 iPad 上没有 Flash。有谁知道还有什么东西可以在不使用 Flash 的情况下使用吗？
也许我不得不承认并为 iOS/Android 编写它。如果是这样，我该从哪里开始那个？
Let me set this up. I work in sound / multimedia at a medium-sized church. There are times when the platform needs to communicate with either the sound room or the multimedia room, and we don't want to be obvious about it. We've tried walkie talkies, but, frankly, we run things pretty hot, and we can't hear the talkies, even with earbuds.
Also, we can't use texting; it's just too slow.
The current working idea is to use some sort of tablets (e.g., iPads) to run a dead-simple application to deliver quick messages by just tapping on icons. For instance, the music director could tap an icon for "sound room", which gives way to a context-specific screen showing sound-related items. He could then tap "piano", then "pulpit monitor", then "up", then "lots", or "drums", "piano monitor", "down", "a little". See where I'm going? It would seem that a native app would be quick and cool (and easy to monetize), but I don't want to learn development on iOS if I don't have to. I'd rather it just be a web app so that I can run it with a Xoom, if and when I buy one. ;-)
I've spent the past couple of years learning Rails, but I haven't ventured into things like EventMachine. I see that "Juggernaut" might fit the bill, but there's no Flash on iPads. Does anyone know of something else that would might fit without using Flash?
Maybe I'll just have to concede and write it for iOS/Android. If so, where do I even start with that?

我认为这实际上取决于您想如何解决这个问题。假设 Web 层应用程序可以接受，我强烈建议您查看 Sencha Touch。您可以相当轻松地为此类事情编写各种命令，并有一个通知页面供其他人查看。如果您以这种方式编写，您可以在几乎任何移动设备（以及计算机）上运行它。
我知道还有其他一些类似的产品（例如 jQuery Mobile），但我觉得 Sencha Touch 可能是目前最成熟的产品。
希望有帮助！
I think it really depends on how you want to approach this problem. Assuming that a web tier application is acceptable, I would highly recommend that you check out Sencha Touch. You can fairly easily program all sorts of commands to that sort of thing, and have a notifications page for everyone else to be looking at. You could run it on just about any mobile device (and computers, for that matter) if you wrote it that way.
I know there are a few others out there that are similar (jQuery Mobile, for instance), but I feel that Sencha Touch is probably the most mature product available at this point in time.
Hope that helps!
